Step by step installing Oracle 11gR2 On Redhat 6

Installing Oracle 11gR2 On RHEL6

During my practies on Oracle i decided to install Oracle 11gR2 On OEL 6.4,
So follow steps and enjoy it :)

The first Step is Download the zip of Linux on oracle site

Oracle’s Technical Network  and downloaded the two Linux x86-64 files for 11.2.0.1.0.
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip

The second Step Prerequisites

Update /etc/sysctl.conf 

Open sysctl with command "vi" and scroll to the bottom write the necessaries

vi /etc/sysctl.conf


kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.ipv4.ip_local_port_range = 9000 65500
fs.file-max = 6815744
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576

Update /etc/security//limits.conf

vi /etc/security/limits.conf

oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

Add users and groups

On Oracle-base you can see some others group whichs are for grid control

The following needed to be added:
groupadd -g 501 oinstall
groupadd -g 502 dba
groupadd -g 503 oper
useradd -u 502 -g oinstall -G dba,oper oracle -p oracle

Create directories and grant permissions

I used my oow directories however you can follow differnts or set like oracle doc.

mkdir /app/oracle
mkdir /u01
chown -R oracle:oinstall /u01
chmod -R 775 /u01
chown -R oracle:oinstall /app/oracle
chmod -R 775 /app/oracle
Switch to the bkup directorywhich is i create before and setup the permissions there: which is i create before
cd /bkup
chown -R oracle:oinstall database
chmod -R 775 database

Set up the oracle user environment

su oracle
vi /home/oracle/.bash_profile


export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=************
export ORACLE_UNQNAME=********
export ORACLE_BASE=/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_SID=********
export PATH=/usr/sbin:$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/lib64
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

AND VERIFY BASH PROFILE WITH FOLLOWING COMMAND

. .bash_profile

Verify and/or install specific dependencies

Oracle has a list of dependencies which have to be verified.  yum are noted with (*):
binutils-2.17.50.0.6
compat-libstdc++-33-3.2.3 (*)
compat-libstdc++-33.3.2.3 (32 bit) (*)
elfutils-libelf-0.125
elfutils-libelf-devel-0.125 (*)
gcc-4.1.2
gcc-c++-4.1.2 (*)
glibc-2.5-24
glibc-2.5-24 (32 bit)
glibc-common-2.5
glibc-devel-2.5
glibc-devel-2.5 (32 bit)
glibc-headers-2.5
ksh-20060214 (*)
libaio-0.3.106
libaio-0.3.106 (32 bit) (*)
libaio-devel-0.3.106
libaio-devel-0.3.106 (32 bit) (*)
libgcc-4.1.2
libgcc-4.1.2 (32 bit)
libgomp-4.1.2
libstdc++-4.1.2
libstdc++-4.1.2 (32 bit)
libstdc++-devel-4.1.2
make-3.81
numactl-devel-0.9.8.i386 (*)
sysstat-7.0.2 (*)

Then proceded with the other dependencies:
yum install unixODBC.x86_64
yum install unixODBC-devel.x86_64
yum install unixODBC.i686
yum install unixODBC-devel.i686

Create a recovery area for backups

I create a recovery area (see the screen shots below) on my backup drive with the following:
cd /bkup
mkdir -p oracle/recovery_area
chown -R oracle:oinstall oracle

The third Step is insall oracle

cd /bkup/database
./runInstaller
The following are screen shots of all the steps I’ve taken with the graphical installer:

If you wanna to take support from Oracle you have to give your mail address which is you already registered on Oracle Support site.

 so I don't fill down Oracle support for this.

 

At this step we see tree installation options so i wanna create with a configuring database, because i would like to show you how to auto create a database after installation, Also i will show you next post Creating A database using DBCA and manually creating a database.

 Here we go, if you are using desktop choose the first, But i'm installing on REDHAT 6 and 40gb and 2gb RAM on Virtualbox :)

 

So, if you have RAC system you can follow the second option, But im just installing a single instances.

Typical is the basic optison so i rather go on Advanced install

 Choose your own language

 

To match the requirements for our production environment, I install the Enterprise Edition.

 

These steps are show you Oracle base path whichs are you wrote in Bash_profile..

This also a directory for files is OraInventory

If you are on Datawarehouse so go on that to create a database.but i used General

I'm always on name ORCL

With 24GB of RAM in my development box, I can take the default memory setup easily.

This is where I choose the UTF8 character set

Here we go again, the important thing is security whatever i will ignore :)

So i dont need any database with sample schemas but i recomend to you use it :)

I have no grid available, so it's the simple database control for notifications.

Our file is system on OS is /u01 

Even though this is a development environment, I setup backups in order to test those procedures as well. This is where I point to the recovery area I setup above.

 Oracle is using, my weak password but it is a strong password none the less (according to many other password checkers).

I use the groups suggested as setup earlier.

 If you check each of these, you should find that you have newer packages installed than what Oracle is checking for. Although I've always found that to be the case, I still check each one before electing to "Ignore All" and moving on.

Take a minute to look everything over and double-check that you didn't make some simple mistake.

Make note of the URL for the Enterprise Manager and move on…..almost done!

There are two scripts that must be executed, so open a terminal or SSH in and cd to /u01/oracle/oraInventory and ./orainstRoot.sh, then cd /opt/oracle/product/11.2.0/db_1 and ./root.sh. Once these have been executed, click Ok.

Congratulations! Time to "get back to work!" :)
